viewing frames of animation
With the default key bindings, F12 will render a frame, and F11 will toggle the render view on and off.  The rendered result is shown in the "UV Image Editor" panel.  In that view, select from the menus Image -&gt; Save As Image to save the one frame.

If you have more than just one or two frames, this will quickly get tedious.  Go into Scene settings, set up an output folder, and you can render a stack of separate frame images in one go.
